Engine builders, listen up! This ARP Two-Bolt Main Stud Kit is built for serious performance and reliability. Each kit includes hardened washers and high-strength hex nuts, so you've got everything you need for installation. The studs are made from 8740 chrome moly steel, which is super tough, and they're rated at a whopping 190,000 psi tensile strength – that's serious durability under high stress. They're precision centerless-ground and thread-rolled to Mil-S-8879 specifications, ensuring perfect fit and consistent quality. The black oxide coating adds corrosion resistance, so they'll hold up well even in demanding environments. Whether you're rebuilding a street engine, a race motor, or just upgrading for extra peace of mind, these main studs provide superior clamping force and stability compared to stock bolts. They help prevent main cap walk and maintain proper alignment under high RPM and load. ARP is a trusted name in the performance industry, known for top-tier fasteners. Installation is straightforward if you're familiar with engine assembly – just make sure to torque them correctly according to ARP's specifications. Upgrade your bottom end with confidence using this pro-grade stud kit. Your engine will thank you!
